Abstract
Choice problems in the spirit of Ellsberg (1961) suggest that rank-dependent ("Choquet expected utility") preferences over subjective gambles might be subject to the same difficulties that Ellsberg's earlier examples posed for subjective expected utility. These difficulties stem from event-separability properties that rank-dependent preferences partially retain from expected utility, and suggest that nonseparable models of preferences might be better at capturing features of behavior that lead to these paradoxes.
